I'm running the last(?) Intel MBP from 2019 for rust and web development and haven't found any reason to upgrade.

Interesting observation: my remote junior colleague has a M2 Pro MBP with more memory than me. We're running the same OSX and node versions. Spinning up a development environment in a project using vite and a Java DB process running inside docker is about 3x faster on my old Intel than on their M2 Pro. The problem isn't anything trivial, and I'm struggling to help them figure it out over Zoom.

Not saying it isn't fixable, but I suspect there are still ARM potholes you trip on.
